The Computer-Human Interface has a new heavyweight contender technology - brain computer interface technology pioneer Emotiv Systems will have its EPOC neuroheadset to market before Christmas 2008. The lightweight US$300 EPOC is worn on the head but does not restrict movement in any way as it is wireless. The set detects conscious thoughts, expressions and non-conscious emotions based on electrical signals around the brain. It opens up a plethora of new applications which can be controlled with our thoughts, expressions and emotions, including for example, the prospect of live animation using the unit’s facial recognition sensors to mimic a gameplayer's facial expressions in an animated avatar.
